Physicist Jim Beale invents a machine capable of creating a wormhole, theoretically allowing for time travel. Determined to prove his invention works and secure funding, he conducts an experiment that successfully pulls a rare dahlia from the future. As he tries to figure out how the flower traveled back in time, Jim encounters a mysterious woman named Abby, who seems inexplicably connected to his work.

As Jim delves deeper into the mystery of the dahlia and Abby's involvement, he discovers unsettling parallels between their interactions and the science behind the wormhole. He becomes increasingly paranoid, questioning the reality he thought he knew. With the boundaries of time blurred and his own sanity on the line, Jim races against both temporal anomalies and adversaries who would use his invention for their own gains. The narrative weaves through elements of love, betrayal, and the ethical quandaries of tampering with time, setting the stage for a dramatic conclusion that redefines Jim's understanding of his work and his place in the timeline.
